Please add tag suport for all transactions.
For example i have business trip, and all expenses during the week I associate with tag #btrip_NY_june.
At the end of fiscal month I'd like to select all transactions with tag #btrip_NY_june and press the button "Refund", that will create new income transactions from my employer.
Tikets booked in may, hotel booked in june, car rented in October.
All food and entertainment expenses during vacation.
If i'll have tag #summer_trip for all this expenses i'll easily calculate real cost of the trip.
